Abstract

PURPOSE:To omit the MODEM of the digital terminal and then to realiize the use of a high-speed digital terminal by securing a switchable connection between a subscriber circuit and the analog terminal of the telephone set or the like plus the digital terminal of the data facsimile or the like. CONSTITUTION:Subscriber's private system 21 containing telephone 4 which can be switched via switch 6 and digital terminal 5 is connected to digital exchange 19 containing digital switch 1 giving a time-division exchange to the digital signal as well as subscriber circuit 3. Then the analog signal sent from circuit 20 is converted via sampling circiuit 13 of circuit 3 into the digital signal to be applied to switch 1, and the signal from switch 1 is converted into the analog signal via decoding circuit 16 to be supplied to circuit 20. And encoding and decoding selection circuits 9 and 10 connected to selection control circuit 18 which gives a selective control to circuit 13 and 16 by the control of control circuit 2 are provided to circuit 3. Thus terminal 5 can be used through a high-speed switching.
